Laser bleaching – the procedure of clarification of enamel of teeth based on effect of oxygencontaining gel and beam of the laser. Allows to bleach teeth with the minimum consequences for their structure.
The attractive smile with ideally equal and white teeth is considered indicator of social prestige today. Any dental clinic renders services in bleaching of teeth and if does not render yet, then for certain it is going to make it as this direction is demanded more than ever. There are several ways of bleaching, and one of them is laser bleaching. What does it consist in?
Bleaching mechanism
First of all the stomatologist attentively studies mouth of the patient regarding cracks of enamel, caries, low-quality restoration and other defects which can affect the end result. Only after receiving full picture the doctor renders verdict about the expected result of carrying out bleaching and possible side effects. To the patient put on goggles on eyes and carry out careful toothbrushing and removal of deposits. Then teeth and gum carefully dry up. The last in addition cover with protective material.
Further apply the special oxygencontaining gel incorporating peroxide of hydrogen on teeth and process the laser within 30 seconds in the same sequence, as well as when putting gel. Under the influence of the laser, gel breaks up to particles. The active oxygen released during chemical reaction deeply gets into dentine and tooth enamel, neutralizing the pigments which are available there giving to teeth yellowish and brown shade. The laser beam at the same time undertakes functions of the catalyst, promoting fast penetration of oxygen into enamel and enhancing effect of bleaching. During all procedure the doctor is guided by condition of the patient: at emergence of adverse or undesirable sensitivity density of energy is reduced or diminish power. At accidental contact of gel with soft fabrics or skin they are immediately covered with thick layer of gel with vitamin E. This strong antioxidant quashes burning sensation and irritations. On the end of procedure gel is removed, and the oral cavity is irrigated. Teeth process gel with fluorine and irradiate for 15 seconds. Fluorine together with laser energy allocates teeth with resistance to future attacks of acids. If the patient remains is dissatisfied with the reached effect, the procedure can be repeated in 2 weeks.
Conclusion
Laser bleaching is rather safe procedure for structures of solid tissue of teeth, soft fabric and live pulp on condition of strict accounting of indications and contraindications and also accurate observance of algorithm of bleaching. The technique allows to achieve long esthetic result at minimal risk and cost.
